Windows 7 - Pre PDC
I continue to read Paul's site and he recently updated his great FAQ article on what to expect for Windows 7. How much is true is probably circumspect - I have yet myself to see the M3 release, but have heard great things.
Now that "7" is now no longer a code name will Brad Pitt, Howard Shore or the Japanese performer Se7en be up for a marketing role?
Seriously though, features I think would be good in Seven (again I haven't heard, seen or can confirm any of this):
Support of lower specification hardware
Hyper-V built in
MinWin or Windows Core
Customised UAC Slider
